SPECIFICATION forming part of Letters Patent No. 758,414, dated April 26, 1904.

Application filed September 30, 19 03- Serial No. 175,185. (No model.) i

To all whom it may concern:

Be it known that 1, WILLIAM L. CARSON, a citizen of the United States, residing at VVinfield, in the county of Cowley and State of Kansas, have invented a new and useful Grain-Oar Door, of which the following is a specification.

My invention relates to grain-car doors, and has for its objects to produce a comparatively simple inexpensive device of this character which may be readily manipulated and one which in practice will entirelyobviate leakage of grain from the car. With these and other objects in view the invention comprises the novel details of construction and combination of parts more fully hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation, of a portion of a car having my improved door applied thereto, the same being viewed from the interior. Fig. 2 is .a similar view taken from the exteriorof the car. Fig. 3 is an inside elevation showing the door open. Fig. 4 is a vertical sectional elevation. Fig. 5 is a horizontal section plan on the line 5 5 ofFig. 1. Fig. 6 is a detail view showing a modification.

Referring to the drawings, 1 indicates the side wall of a car provided with a door-opening 2, at the sides of which there is disposed a pair of frame-bars 3 4, extending vertically between and secured to the upper and lower sills, conjointly with which latter they form the door-casing. These parts may be of the usual or any preferred construction, inasmuch as they constitute no part of my invention.

5 designates my improved door, adapted to close between the bars 3 and 4. and when closed to bear at its outer face against jambs or abutments 6, attached to the oppositely disposed faces of the bars 3 and 4. The jambs 6, the active faces of which extend at right angles to the adjacent faces of the frame-bars, are so positioned that when the door 5 is closed against them its inner face will lie flush with the inner face of the car-wall, or, in other words, that the door when closed seats within the opening 2 and has bearing at its ends against the frame-bars and at its outer face upon the jambs, being in this manner so sealed as to eflectually prevent a leakage of grain. 5 The door 5 is preferably composed of an upper section 7 and a lower section 8, seated vertically one above the other, the lower. edge of section 7 having appliedthereto a strip 9, secured by screws or otherwise and designed to overlap the upper edge of section 8, thus preventing leakage of grain between the sections. Attached to the frame-bare or adjacent framework are hinge-leaves 10 and to the adjacent edge of the door coincident leaves 11, said leaves 10 11 having vertically perforated and alined knuckles 12, through which extends a pivoting-rod 13. The rod 13, which is removable, is in the present instance composed, preferably, of two sections provided 5 one for each of the door-sections 7 8, and upon the upper end of each rod-section is formed a head 14, which bears upon the adjacent knuckle 12, thus limiting the downward movement of the rod while the rod is 7 normally secured against Withdrawal by means of a cotter-pin 15, bearing beneath the adjacent knuckle 12. It is apparent from this construction that the door as a whole or either of its sections is free to swing to an open position and that when circumstances require during the operation of loading and unloading the car the rod 18 may be readily withdrawn, thus permitting the door to be wholly removed. It is also to be observed that the disposition of the hinge-leaves is such as to permit bodily elevation of the door in a vertical plane -to permit outflow or discharge of the grain beneath the door or for the purpose of seating the latter when in an open position 5 upon a pair of supporting brackets or membelfi 16, attached to the inner face of the carwa Pivoted to the frame-bar 3 and arranged one for each of the door-sections is a pair of 9 door-engaging members or cleats 17, designed when the door is closed to swing into engagement therewith and serve as guides for the door when elevated within its opening in the manner above explained.

For locking the door and holding it downward upon its sill I provide a series of locking or engaging members 18, preferably in the form of hooks pivoted to the door and adapted to be engaged with suitable catches or devices 19, preferably in the form of eyes screwed into the door-jambs. The eyes 19 are placed at a lower level than the pivotal point of the hooks 18, whereby the latter in engaging the eyes exert a downward pull upon the door, thus preventing the latter rising, owing to jarring of the car, and at the same time seating the lower edge of the door firmly upon the bottom sill to prevent leakage of grain at said point. In this connection it is to be noted that other forms of locking devices may be substituted for those herein shown or that, if preferred, the hooks may, as illustrated in Fig. 4, be pivoted to the doorjamb and the eyes carried by the door.

Attached to the inner face of the car-wall is a vertical beam 20, which when the door is open and seated upon the brackets 16 lies at the outer edge of the door. This beam carries projecting members 21, preferably in the form of screws tapped into the beam, designed for engagement by the hooks 18 for securing the door in its open position.

Formed in the outer face of the door adjacent to its lower edge is a pair of sockets 22 to be engaged by a tool for lifting or elevating the door.

In practice supposing it to be desired to discharge grain from the car the door is first elevated in the manner heretofore explained, thus permitting the grain to escape beneath the door. After as much grain as possible has been discharged in this way the door is then swung to an open position and seated upon the brackets 16, thus permitting the remaining grain to be shoveled or otherwise discharged through the door-opening.

From the foregoing it will be seen that I produce a device of simple construction which is admirably adapted for the attainment of the ends in View; but I do not limit myself to the precise details herein set forth, as minor changes may be made within the scope of the invention.

Having thus described my invention, what I claim is 1. The combination with a car, of a door and its casing,supporting-brackets sustained upon the interior of the car, hinge members attached to the door and easing, a pivoting-rod extending through said members, the latter being relatively disposed to permit bodily upward movement of the door to seat upon the brackets, locking members carried by the door, and devices carried by the car and adapted for engagement by the locking members for securing the door in either its open or closed position.

2. The combination with a car having a doorway, of a door comprising a pair of sections disposed vertically one above the other, hinge members carried by the respective door-sections and car, and a pivoting-rod extending through said members, the latter being rela' WILLIAM L. CARSON.
